To all whom it may concern:

Be it known that I, WALno G. FAY, a citizen of the United States, residing in Pelham,

Westchester county, and State of New'York, have invented certain newand useful Improvements in Guard-Plates and Bearing- Pads for Eyeglass-Mounts, of which the fol lowing-is a specification. I

My "mprovements relate to guard plates and bearingpads used in eye glass'mounts,- the guard plates to which the bearing padsare connected being secured to the lens posts as heretofore.

The object of my invention is primarily to afford a bearing pad which is free to adapt itself independently within certain prescribed limits, both longitudinally'and laterally upon, and as related v to, the guard plate on which it is mounted, in such manner that said bearing pad may conform read:

ily and perfectly to the curvature of surface to which it may be applied (as the nose of the user) whether sald surface be concave or convex or inclined laterally with relation to the guard plate; and secondarily to af ford twin bearing pads of such character on each guard plate, all as hereinafter dey scribed and claimed specifically.

In the accompanying drawings, which show the parts enlarged for convenience of illustration, Figures .1 and 2', are, respectively elevations of opposite sides 'of what may be designated as the left hand guard 3, an edge view of the same; ngitudinal section upon plane of late; Fig. ig. 4, a

line 44 Fig. 2;. Fig. 5, a transverse section upon plane of line 55 Fig. 2; Figs.

6 and 7, are views similar'to Figs. 1 and 2,

With the bearing pads attached; Fig. '8, is

.an edgeview of Fig. 7 Fig. 9, a section upon plane of line-9'9-' Fig. 7; Fig. 10, is a sec* tion upon plane of line 10 '10 Fig. 7 Figs. -11 and 12,. are elevations similar to.

Figs. 6 and 7, showing the use of a special form of bearing pad; Fig. 13, is a view of the inner side of such a bearing pad; and

made in rights and efts, -but'are otherwise- .mounted. I

a curvature of surface to which the pads may slots .4' irit the same in structure, consisting of the perforated shank 1, and the elongated bearing plate 3, upon which the bearingpads P are The elongated bearing plate?) 'is formed with longitudi-nal slots 4 near each extrem ity which are preferably in'the same longitudinaLplane/ The ortions of the plate 3,.

adjoining each of t ese slots 4 are'bent to form'a concavity'fi, on one side of the said 'plate'3,-an"d a convex surface 6 on the. other side thereof. a

.. Each bearing pad P is preferably formed of :one'piece,.with a rearwardly projecting stud 70.

1), adapted to' project through one of the elongatedslots 4 in the plate 3, and to have its end upset or peaned over to form ahead 10, as in Figs. 7 to 1 0 inclusive; or when the pad P is made of suitable material, studs 1),

may be cut and bent out ofthe body of the pad,- and the ends thereof bent over to form flanges or heads p",as in Figs. 12 to 14 inclusive. In either case the heads p, or p, lock the bearing pads P loosely in position upon,

the plates 3, ut donot prevent the said bearing pads P adapting themsclvesboth laterally and longitudinally to any inclination or be applied in use.

The requisite lateral play,of the bearing padsis necessarilybut slight, so that the difference between the width of the slots 4, and the thickness of the studs p, is. sufficient to afford all the loosenessi that is desirable in this res ect; but a much greater degree of' longitu inal play and flexibility is desirable in so far. as the bearing pads P are concerned and this is provided for by the longitudinal the'curvature of the ortions of the plate 3 adjoiningthe longitu inal slots 4, is important in that it augments the scope of inclina-' tion and play afforded the bearing pad. .It

will be noted that these ,twin pads P, articu 0 late independently upon each guard late G, are in alinernent with each other, an are the only contacts or bearings employed by me,

'my object being purposely to' avoid and dis-- y pense with rigid unyielding bearing surfaces such as heretofore used.

. I am awarethat articulated bearings have heretofore been used in conjunction with rigid bearings, and I do not seek to cover an articulated bearing broadly, but'only my special construction and arrangement of independently articulated twin bear ng-pads,

e plates 3Q "In thisconnection as herein set forth, whereby the mount is adaptednot only to the longitudinal curva-- ture of the opposed surface of the nose of the user, whether convex or concave, or both, but also to lateral curvature as well, and in this connection it is important to note that this lateral adaptability of the bearing pad acts constantly to retain the glasses against accidental displacement or forward sli upon the nose of the user, because any lateral movement causes the bearing ad to tilt over so that its edge will press or dig into the adjoining flesh of the nose, and thereby prevent sli and dis )lacernent.

hat I claim as my invention and desire to secure by Letters Patent is,

1. A guard plate for eye glass mounts con sisting of a shank and an elongated bearing plate formed with an elongated slot near each extremity, and bearing pads formed with rearwardly projecting shanks projecting through. said elongated slots in the bearing plate said. shanks being of less diameter than the widthof the slots and being headed to revent their withdrawal therefrom, wherey the bearing pads are rendered capable of movement longitudinally upon the bearing plate and also are capable of lateral 'play thereon, for the purpose described.

2. A guard for eye glass mounts consisting of a shank and an .e ongated bearing plate 'elongated slots, an

formed with portions which are concave onone side and convex on the other, said portions of the bearing 713116 being formed with bearing MlS formed with rearwardly projecting shanlrs projecting through said elongated slots in the bearing plate said shanks being of less diameter than the Width of the slots and being headed to revent their withdrawal therefrom, where- )y the bearing pads are rendered capable of movement longitudinally upon the bearing plate and also are capable of lateral play thereon, for the purpose described.

3. The combination with a guard plate of the character designated formed with a portion concave on one side and convex on the other, said portion being formed with an elongated slot, of a one piece bearing pad formed with shank passing through said elongated slot said shank being of less diameter than the width of the slots and being headed to prevent its withdrawal therefrom, whereby the bearing pad is rendered capable of movement longitudinally within the slot and is also capable of lateral play upon the guard "plate, for the purpose described.
